ASTM A53 Gr.Bndi imodzi mwa miyezo ya chitoliro chachitsulo yopangidwa ndi American Society for Testing and Materials (ASTM). Izi ndi chiyambi chatsatanetsatane cha chitoliro chachitsulo chopanda msoko cha A53 Gr.B:
1. Chidule
Chitoliro chachitsulo chosasunthika cha ASTM A53 Gr.B. Pakati pa miyezo ya chitoliro chachitsulo yopangidwa ndi American Society for Testing and Materials (ASTM), ASTM A53 yagawidwa m'magawo awiri, A ndi B. ASTM ikuyimira seti ya miyezo yaku America. Muyezo wofanana wa ku China wa A53A ndi GB8163, womwe umapangidwa ndi chitsulo Nambala 10, ndipo muyezo wofanana wa ku China wa A53B ndi GB8163, womwe umapangidwa ndi chitsulo Nambala 20. Umagwiritsidwa ntchito makamaka pa mapaipi ogwiritsidwa ntchito wamba.
2. Njira zopangira
ASTM A53 Gr.Bmakamaka amagwiritsa ntchito ukadaulo wa mapaipi wopanda msoko popanga mapaipi. Ukadaulo wa mapaipi wopanda msoko umatanthauza njira yosinthira billet kukhala chitoliro chachitsulo chokhala ndi makulidwe ofanana a khoma komanso malo osalala amkati ndi akunja kudzera munjira monga kuboola billet, kugwedezeka, ndi kukula kwa mainchesi. Ngakhale muyezo wa ASTM A53 umalola kugwiritsa ntchito ukadaulo wa mapaipi olumikizidwa popanga mapaipi achitsulo, popangaASTM A53 Gr.B, ukadaulo wa mapaipi wopanda msoko ndiye njira yayikulu yopangira.
3. Zinthu Zogulitsa
Kukhuthala kwa khoma ndi kulondola kwa dayamita yakunja: Kukhuthala kwa khoma ndi dayamita yakunja ya chitoliro chopanda msoko cha ASTM A53 Gr.B kuli ndi kulondola kwakukulu ndipo kumatha kukwaniritsa zosowa za nyumba zosiyanasiyana zovuta.
Kukana kupanikizika kwambiri komanso kukana dzimbiri:ASTM A53 Gr.BChitoliro chopanda msoko chimakhala ndi kukana kwamphamvu kwa mpweya komanso dzimbiri, ndipo chimatha kugwira ntchito mokhazikika kwa nthawi yayitali m'malo osiyanasiyana ovuta.
Kugwiritsa ntchito kwakukulu: Chitoliro chopanda msoko cha ASTM A53 Gr.B ndi choyenera pamakina apaipi otumizira gasi, madzi ndi madzi ena, kuphatikizapo kugwiritsa ntchito m'mafakitale, madzi ndi makina otenthetsera.
4. Mtundu wokhazikika
Muyezo wa ASTM A53 GRB umagwiritsidwa ntchito pa mapaipi olunjika (opindika) ndi achitsulo cha kaboni chopanda msoko, omwe amaphimba mainchesi osiyanasiyana akunja, makulidwe a makoma ndi njira zowakonzera. Malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchito, mapaipi okhazikika a ASTM A53 GRB amathanso kupakidwa galvanized, planed, clothed, ndi zina zotero kuti awonjezere kukana dzimbiri komanso nthawi yogwira ntchito.
